OK here are most of my niggles. Some have already been discussed in the forums.
My first attempt to access stuff in the boot resulted in a cut to my forehead from the sharp edge of the parcel shelf. I have put a length of polystyrene pipe insulation on it. Not on my forehead, on the edge of the parcel shelf. :-)
Cruise control. On my Accord when I held my finger on the accelerate button, the car would begin to accelerate. When I reached the desired speed (as indicated on the speedometer, there was no digital readout) I would let go of the button and the car would continue at the set speed. On the Jazz, if I hold down the accelerate button the digital readout goes whizzing up far ahead of the actual speed of the car. It would be much better (safer) for the digital setting to increase at the same rate as the car.
The integration between the buttons on the left of the steering wheel for audio and phone and the screen displays seem poor to me. I don't think it is possible for example to turn RDS traffic announcements on or off using the buttons and it would be very useful to be able to do that. As it is, I have to park up and fiddle with the screen interface to turn RDS on and off.
Headlight behaviour. This has been well covered in the forum I think.
Dip stick difficult to read. This has also been discussed already I think.
